Plot

Mark Prescott is not in Odyssey anymore. The Imagination Station has propelled him back in time to the era of brave knights, great castles, an evil nobleman, and a good king. Now Mark finds himself in the middle of a quest for the king to retrieve a precious ring. But first he has to survive the wicked Sir Cardoc's plans for him! And then he and the valiant Sir Owen will have to find and do battle with the most dangerous creature in the realm.

Notes

This book is rather similar to The Castle in the Attic in places (though it manages to set itself apart rather admirably anyway).
